Method and apparatus for generating velocity commands in response to rapid changes in operator inputs

摘要

A control apparatus for a continuously variable transmission is disclosed. The control apparatus includes a transmission speed sensor which generates actual velocity signals in response measuring a speed of an output shaft of the continuously variable transmission. The control apparatus further includes a first input device which is positionable in one of a number of positions and generates a desired velocity signal corresponding to the one of the number of positions. The control apparatus yet further includes a controller operable to receive the desired velocity signals, receive the actual velocity signals, determine when rapid changes in the desired velocity are requested by an operator, and generate a commanded acceleration and a commanded velocity based on a jerk value which exceeds a predetermined jerk limit in response to the rapid changes in the desired velocity. A method of controlling a continuously variable transmission is also disclosed.
